  <div>
   <p>If the capacity of a LUN corresponding to the datastore where a VMware VM resides is expanded, you need to scan the LUN again on the host where the client is installed by referring to the following steps. Otherwise, the backup job will fail.</p>

    <h4 class="sectiontitle">Procedure</h4>
    <ol>
     <li><span>Use PuTTY to log in to the host where the client is to be installed as user <strong id="EN-US_TOPIC_0000002164654270__en-us_topic_0000002164790296_en-us_topic_0000002200031305_b916917212">root</strong>.</span></li>
